TranscriptomicsRNA-seq of human colorectal cancer HCT116 and HT29 cells by the distinct conditions of trypsin digestion
In the process of cell culture in vitro, we usually find that the cells show signs of aging, which is that the passed cells are unable to stick to the wall. Experience tells us that the time it takes for trypsin to digest the adherent cells is important. If the digestion time is too short, enough ce...

ProteomicsTandem LysC/trypsin digestion performs efficient in detergent conditions and under constant denaturating environments
All shotgun proteomics experiments rely on efficient proteolysis steps for sensitive peptide/protein identification and quantification. Continuous protocol improvement is therefore a constant topic in proteomics research. Previous reports suggest that the sequential tandem LysC/trypsin digest yields...

Immunoprecipitation-mass spectrometry (IP-MS) has become the method of choice for discovering protein-protein interaction (PPI) under native conditions. The success of the IP-MS depends on the efficiency of trypsin digestion and recovery of the tryptic peptides for MS analysis. Several different pro...

ProteomicsRapid trypsin digestion at elevated temperature with calcium for enhanced bottom-up proteome analysis
Trypsin is frequently employed to cleave proteins ahead of mass spectrometry characterization. Traditionally, enzyme digestion involves overnight incubation of proteins at 37 °C, which is not only time consuming but can still yield in poor digestion efficiency. While raising the temperature should t...

ProteomicsProteomics Using Proteases Alternative to Trypsin Benefits from Sequential Digestion with Trypsin
High specificity and ease of use make trypsin the most used enzyme in proteomics. Proteases with complementary cleavage specificity to trypsin have been applied to obtain additional data. However, use of proteases with broad specificity proved especially challenging. In this work, we analyzed the ch...

ProteomicsEvaluation of the Effect of Trypsin Digestion Buffers on Artificial Deamidation
This work comprehensively compared 50 mM of ammonium acetate (pH 6), Tris-HCl (pH 8), ABC and TEAB as in-solution trypsin digestion buffers. Both iTRAQ quantification and label-free results indicate that ammonium acetate (pH 6) is more suitable than other buffers for studying endogenous deamidation ...
